Specification of Lettersratent.

"a lication filed June 9,1915. semi No. 33,111;

signed and adapted for use in connection with hay wagons; and it is an object ofmy invention to provide a novel and improved draft rigging whereby the same maybe readily and effectively 'controlled' by the driver without the necessity of leaving the' seat. p

The invention consists in the details of construction and in the combination and arrangement of the several parts of my im-' proved brake mechanism whereby certain important advantages are attained andthe device is rendered simpler, less expensive and otherwise more convenient and advantageous forruse, all as will be hereinafter more fully set forth.

The novel features of the inventionwill be carefully defined in the appended claims.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a view, partly in elevation and partly in section, illustrating a brake mechanism constructed in accordance with an embodiment of my invention in applied position; Fig. 2 is a view in perspective of the parallel straps together with their concomitant parts as herein embodied; and Fig. 3 is a view in perspective, detached, of the locking dog herein included.

As disclosed in the accompanying drawings, 1 denotes the rear bolster of a conventional hay wagon or the like and with which coact, in a conventional manner, the wheels 2.

3 denotes the side sills or ladder rails, to the rear extremity of one of which is secured the shoe or casting 4 from which depends on a predetermined incline the spaced straps 5.

6 denotes a hanger iron depending from the sill or rail 3 in advance of the shoe or casting 4 but in close proximity thereto and to the lower extremity 'of said hanger iron" is pivotally 'engaged'the upstanding arcuate" r. PatentedFeb. 22, 1916.,

extension 7 of the'lever 8, said lever hav-y ing its rear extremity providedwith the upstanding extension 9 passing hetweenthe i straps and having sultably secured to its;

free extremity the'fiex'ible member 10. lead' ing to the seat structure (not shown) of the *Wagon. I r

11 denOtesthe rock shaft of a conventional brakemechanism adapted to coact with the wheels 2, and 12 is, an operatinglever' interposed between the rock arm 14 of the shaft 11 and the arcuate extension 7 whereby it will be perceived that upo'n'upward movement' being given to the lever 8, the brake mechanism will be caused lto operatively; Y

engagefthe wheels 2.

Operatively supported tremities of the straps 5 is the shaft 15 to vby'the lower ex which is atfixed the upstanding dog 16'. 4

adapted to coact with the rack portion 17 provided at the outer edge of the extension 9 and whereby it will be perceived that the brake mechanism may be locked in operative engagement with the wheels 2. The shaft is provided with arock arm 18 to the; free extremity of which is secured a flexible member 19 also leading to the seat structure of the wagon and whereby it will be perceived that the dog 16 maybe readily disengaged from the rack 17 when it is desired to release the brake.

In order to limit the downward movement of the lever 8, I provide the extension 9 with the inwardly disposed projection 20 adapted to engage the pin 21 bridging the space be tween the straps 5 adjacent their upper extremitiesa I also find it of advantage to provide the straps 5 with the outstanding yoke 22 whereby the dog 16 has its outward movement so limited as to prevent the same from passing beyond a center and thus aschange and modification without material d p rture from the principles and p t thereof and for this reason I do not Wish'to' be understood as limitingjniyself to the preelse arrangement and format on oi theseveral parts herein shown in carrying out my the swinging plate 23 pivotally engaged, as

at 24, with one of the straps 5 and normally locked in, operative position through the medium of aconventional bolt25 'or the e t s a solto, ob e ed at h p ate,
